Introduction
Introduction
The Schneider Monoflanges and VariAS-Blocks are designed to overcome the problems of traditional assemblies on primary isolation duties. By combining piping and instrument valves in a single assembly, they provide weight and space savings, along with other benefits

including reduced potential leak points and safer hook-up. This more compact and efficient arrangement reduces not only pipework vibration and associated stress but also installation and maintenance costs.

Process MonoflangesDesigned to replace the traditional primary isolation valve, the Primary Isolation Valve (OS&Y bolted bonnet) incorporates a primary isolate piping valve combined with instrument double block & bleed functions.
Instrument MonoflangesInstrument Monoflanges work in conjunction with a pre-installed primary valve to provide a compact instrument block and bleed valve or are used when primary valves with an OS&Y bolted bonnet are not required.

VariAS-Block Series
VariAS-Block Series
The VariAS-Block Series are designed to replace conventional, multiple-valve installations. The VariAS-Blocks are forged, one-piece double block and bleed assemblies for primary isolation of pressure take-offs, where the valve is
directly mounted to the vessel or process pipe. Instruments may be directly mounted to the valve outlet or remote mounted with impulse pipe work.
Features two independently operable ball valves for isolation with an intermediate needle valve alternatively ball valve for venting.
